Reddit's image handling varies dramatically by subreddit: some allow galleries, others enforce strict single-image submissions, and many heavily restrict external links. When you need to show a sequence, a comparison, or multiple angles, hitting the one-image limit is frustrating. A merged grid is the universal workaround. A 2×2 grid showing four stages of a DIY project, a 1×3 strip comparing three product variants, or a 3×3 grid documenting a restoration journey — all become valid single-image submissions that carry far more information than any standalone photo. The format is particularly effective on visual-heavy subreddits like r/pics, r/DIY, r/mildlyinteresting, r/oddlysatisfying, and r/BeforeNAfter. On advice-oriented subreddits like r/relationships or r/legaladvice, a grid of screenshots (with usernames redacted) provides full context in a single view. For gaming communities, a 2×2 showing build stats, inventory, map location, and combat result tells a complete story. The key to Reddit grid success is legibility at thumbnail size: Reddit's feed displays images at roughly 300–400px wide, so use 4–8px cell spacing and ensure each cell is visually distinct. Export at 2000px so the full-resolution image holds up when users click to zoom. MergeFrame's zero-upload architecture is critical for Reddit users who frequently share screenshots containing personal information — your images never touch a server before you post.
